Answer:
Answer: the height of cylinder A 16 inches.
Step-by-step explanation:
1.4h_A=5.6\cdot 4,\\ 1.4h_A=22.4,\\ h_A=\dfrac{22.4}{1.4} =16 in.
Answer: the height of cylinder A 16 inches.
Answer:1 inch
Step-by-step explanation:
3x - y = 0 ⇒ 2(3x - y = 0 ) ⇒ 6x - 2y = 0
5x + 2y = 22 ⇒ 1(5x + 2y = 22) ⇒ <u>5x + 2y</u> = <u>22 </u>
11x = 22
x = 2
3x - y = 0 ⇒ 3(2) - y = 0 ⇒ 6 - y = 0 ⇒ 6 = y
Answer: x=2, y=6
Answer:
x=2
Step-by-step explanation:
2x+10=14
2x=14-10
2x=4
x=4/2
x=2
1/2x-2/5=3/5 (BTW I got 2/5 by reducing 4/10)
1/2x=7/5 (BTW I got 7/5 by moving 2/5 to the other side)
Then do 7/5 times 2 and you get 14/5
14/5
